OVAPLANT® is the brand name for a "pellet implant" containing Salmon Gonadotropin - Releasing Hormone analogue (sGnRHa).

OVAPLANT® is effective in synchronizing and advancing maturation and ovulation in many fish species.  It is injected as a single implant dose prior to normal spawning.  The product is in pellet form and is injected into the fish using a Ralgun Implanter.

OVAPLANT® can be used to:

  • Induce maturation in advance of the spawning season
  • Coordinate and synchronize spawning times
  • Increase milt production including increased sperm count
  • Induce maturation in difficult species
  • Overcome handling shock or arrested maturation

Environmental and physiological conditions will affect the response to OVAPLANT® and other spawning aids.  Ensure that an adequate ratio of males and females are induced at the same time.  Store sealed OVAPLANT® cartridges at refrigerated temperature (2-8°C) and protect from sunlight.

OVAPLANT® is available exclusively through Syndel.

In the United States, if the intended OVAPLANT® use is to treat food fish, or fish for release into the wild, then it must be used according to the FDA's guidelines for Investigational New Animal Drug Application (INAD) # 11-375.  More information including INAD application forms, study protocols, study summaries etc. can be obtained from the U.S. Fish & Wildlife Service's office of Aquatic Animal Drug Approval Partnership Program (AADAP).  The AADAP office has streamlined the INAD process and the staff there are very helpful.  The AADAP office can be accessed at www.fws.gov/fisheries/aadap/sGnRHa.htm
